Resource origin locations for ID Logic Locked partitions?

Not sure what you mean by resource origin information. If you mean the LLR location, that should be in the LLR window, which I keep up alongside the Chip Planner. If you just mean generally where logic is, you can edit the layers on the top right and turn on the co-ordinates(it's about halfway down the list), so every lab, memory and DSP block is super-imposed with it's X/Y co-ordinates. It's a little cluttered, so I only turn it on when placing LLRs.

I used the old floorplanner all the time, and for the most part find I can do the same stuff in the Chip Editor. It didn't make sense to work on two separate tools that did almost identical stuff. I do believe improves are being worked on for the chip planner to make it more intuitive, but don't think it will be any time soon. But again, I've been able to do almost everything I did in the old one(along with many new capabilities).
